Abstract (en)
[origin: US2010046267A1] A storage system includes a three-dimensional memory array that has multiple layers of non-volatile storage elements grouped into blocks. The blocks are grouped into bays. The storage system includes array lines of a first type in communication with storage elements, array lines of a second type in communication with storage elements, and sense amplifiers. Each block is geographically associated with two sense amplifiers and all blocks of a particular bay share a group of sense amplifiers associated with the blocks of the particular bay. The system includes multiple sets of local data lines in one or more routing metal layers below the three-dimensional memory array and multiple sets of global data lines in one or more top metal layers above the three-dimensional memory array. Each set of one or more blocks include one set of the local data lines. Each bay includes one set of global data lines that connect to the group of sense amplifiers associated with the blocks of the respective bay. Each block includes a subset of first selection circuits for selectively coupling a subset of array lines of the first type to respective local data lines. Each block includes a subset of second selection circuits for selectively coupling a subset of the respective local data lines to global data lines associated with a respective bay.
